Commercial arbitration in Kenya has no fixed statutory finish line — the Arbitration Act, 1995 sets deadlines for challenging an award, not for closing the case. A straightforward single-arbitrator dispute run under institutional rules commonly wraps up within about 12 months of the tribunal's appointment; a three-member tribunal handling a document-heavy claim routinely runs past 18 months, sometimes into a second year, before a final award lands in 2026. The number that trips people up: once you receive that award, Section 35(3) of the Arbitration Act, 1995 gives you exactly three months to ask the High Court to set it aside — miss that window and the award is final, win or lose.

- Section 35(3) of the Arbitration Act, 1995 gives either side just three months to apply to set aside an award after receiving it.
- There is no appeal on the merits — courts can only set an award aside on narrow procedural grounds, not re-decide who wins.
- Institutional arbitration through a body like the Nairobi Centre for International Arbitration generally moves faster than ad hoc arbitration with no set procedure.

Why this matters
A business owner weighing arbitration against a court case is really weighing cash flow against certainty. Kenya's courts are slower for commercial matters once appeals get involved, and a supplier dispute sitting unresolved for two or three years can drain a smaller company's working capital long before either side gets a decision.
Arbitration was written into Kenya's legal system specifically to shortcut that delay, but the shortcut only works if the arbitration clause in your contract is drafted properly and both sides cooperate on appointing a tribunal. If you're staring at a stalled negotiation right now, a short conversation with an LSK-verified advocate on Lex Africa can tell you within 15 minutes whether your contract even has an enforceable arbitration clause worth using.
How long does commercial arbitration take in Kenya?
The honest answer: it depends on three things — how many arbitrators sit on the tribunal, whether you're using institutional or ad hoc rules, and whether the losing party challenges the award afterward. Here's how the stages typically break down in 2026.
| Stage | What happens | Typical timeframe |
|---|---|---|
| Tribunal appointment | Parties agree on an arbitrator, or the High Court appoints one if they can't | 1-3 months |
| Pleadings and hearings | Statements of claim and defence, document exchange, hearing dates | 4-12 months |
| Award issuance | Tribunal deliberates and issues a written, binding award | 1-3 months after final hearing |
| Post-award challenge (if filed) | Losing party applies to set aside under Section 35 | Must be filed within 3 months of receiving the award |
A case that moves through the first three rows without a challenge can be done in under a year. A case where the losing side fights the award in the High Court easily adds several more months, and longer again if it reaches the Court of Appeal.
Institutional arbitration: often under 12 months
Running your dispute through a recognised body like the Nairobi Centre for International Arbitration (NCIA) means you work inside published rules with built-in case-management deadlines instead of negotiating procedure from scratch. That structure is the main reason institutional cases tend to close faster than ad hoc ones.
Best for: businesses that want predictable milestones and a tribunal used to commercial disputes. Verdict: recommended for contracts of meaningful value where speed and enforceability both matter.
Ad hoc arbitration: often 18 months or more
Ad hoc arbitration means the parties and the tribunal set every procedural rule themselves — timelines for pleadings, how hearings are scheduled, even how the arbitrator is replaced if they step down. Without an institution enforcing deadlines, delays compound. One side stalls on document production, a hearing gets rescheduled twice, and a case that should have taken a year drifts toward two.
Best for: parties with a working relationship and genuine interest in cooperating on timelines. Verdict: proceed with caution — build strict deadlines into the arbitration clause itself if you go this route.
Court challenge to an award: a 3-month filing window
If either party applies to set aside the award under Section 35 of the Arbitration Act, 1995, that application must be filed within three months of receiving the award. The High Court hearing and ruling on it adds its own time on top, depending on the court's calendar.
Grounds are narrow: incapacity of a party, an invalid arbitration agreement, lack of proper notice, an award going beyond the scope of the arbitration agreement, or an award that conflicts with Kenyan public policy. Courts do not re-examine who was right on the facts.
Verdict: a set-aside application is a real option when the process itself was flawed, not a second bite at the merits.
Why arbitration timelines vary
- Number of arbitrators — a sole arbitrator decides faster than a three-member panel that needs internal deliberation time.
- Institutional vs ad hoc rules — bodies like the NCIA enforce case-management deadlines; ad hoc cases rely on party cooperation.
- Complexity of the claim — a straightforward payment dispute moves faster than a multi-issue contract dispute with expert witnesses.
- Document production disputes — one side dragging its feet on disclosure is among the most common causes of delay.
- Availability of the arbitrator and counsel — busy advocates and arbitrators juggling several matters push hearing dates further out.
- Whether the award gets challenged — a Section 35 application adds months even when it ultimately fails.
Is arbitration faster than going to court for a commercial dispute in Kenya?
Generally yes — arbitration skips the multi-tier court hierarchy and the appeal stages that slow commercial litigation in the High Court and Court of Appeal. The tradeoff is that tribunal fees, institutional fees and venue costs are paid by the parties directly, so speed carries an upfront cost that a court filing does not.
Can you appeal an arbitration award in Kenya?
No. There is no appeal on the merits of an arbitration award in Kenya. The only route is a Section 35 application to set the award aside on narrow procedural grounds, filed within three months of receiving it, and a successful application usually sends the matter back for re-arbitration rather than producing a court ruling on who was right.
What happens after the award if nobody challenges it?
The award becomes final and is enforced through the High Court as if it were a court decree. If your dispute is really about unpaid invoices, that enforcement step is the whole point — a business weighing its options against debt recovery lawyers in Kenya should know an arbitration award is enforced, not re-litigated from zero.

FAQ
How long does commercial arbitration take in Kenya?
Commercial arbitration in Kenya typically takes about 12 months for a single-arbitrator case under institutional rules and 18 months or more for a multi-arbitrator, document-heavy dispute in 2026. There is no fixed statutory deadline for the process itself, only for challenging the award afterward.
Is arbitration faster than court litigation in Kenya?
Yes, arbitration is generally faster than commercial litigation in Kenya because it skips the multi-tier court appeal process. The tradeoff is that parties pay tribunal and institutional fees directly.
Can an arbitration award be appealed in Kenya?
No, there is no appeal on the merits of an arbitration award in Kenya. A party can only apply to set the award aside under Section 35 of the Arbitration Act, 1995, within three months of receiving it, and only on narrow procedural grounds.
How is an arbitrator appointed if the parties disagree in Kenya?
If the parties cannot agree on an arbitrator, either side can apply to the High Court under the Arbitration Act, 1995 to have one appointed. This step typically adds one to three months to the overall timeline.
What is the Nairobi Centre for International Arbitration?
The Nairobi Centre for International Arbitration (NCIA) is Kenya's institutional arbitration body, administering domestic and international commercial disputes under published rules. Cases run through the NCIA generally move faster than ad hoc arbitration because of built-in case-management deadlines.
Is arbitration cheaper than litigation in Kenya?
Not necessarily. Arbitration often resolves faster, but the parties bear tribunal, institutional and venue fees directly, which can make it more expensive upfront than a court filing even when it finishes sooner.
Can arbitration be used to recover unpaid debts in Kenya?
Yes, if the underlying contract contains an arbitration clause covering payment disputes. Once an award is issued, it is enforced through the High Court as a decree.
What if my contract has no arbitration clause?
Without an arbitration clause, the dispute goes to court unless both parties agree in writing to arbitrate after the dispute arises. An advocate can confirm what your contract actually allows before you file anything.
One last thing
The detail most business owners miss until it is too late: the three-month window under Section 35(3) starts running the moment you receive the award, not when you get around to reading it carefully or finding a lawyer. If you are on the losing end of an award in 2026 and believe the process itself was flawed, get advice within days, not weeks. That clock does not pause for anyone.
